It all started when the Noah attacked. They surprised the Order by appearing in the Ark, taking the science division off guard. They were all murdered without mercy, the Noah not letting anyone live. Once the Exorcists arrived, it was way too late. Allen Walker ran to the science division as fast of he could, but stopped dead when he saw the horrifying scene. The scientists were already dead, the Noah that were still present had mutilated their bodies. Once Kanda arrived, he instantly fought the remaining Noah, Jasdevi, who played along. Allen's silver eyes found Tyki Mikk's golden ones, who smirked as he wiped some blood off his hand. Allen's eyes flashed golden for second before his Innocence activated and he attacked. Soon, both Noah and Exorcist were exhausted, having fought at their max the entire time. Allen gasped for air as Tyki's hand invaded his body and squeezed his heart tightly. His vision became dark as he struggled in the Noah's grasp, but to no avail. His consciousness faded as his heart was beating rapidly, trying to get the intruder out. His last image was Tyki smirking at him, before he heard a scream, "ALLEN!"
He woke up with a start, instantly jumping up as his consciousness returned, but he moved too soon. He stumbled as he found his footing, only to slip on something on the ground. He let the world sway and stop before opening his eyes, only to wish he never did. Actually, he wished he died and never woke up. On the ground was Lenalee, her blood what he slipped on. He fought the urge to cry as he saw his first friend from the Order dead, staring at the spot he was laying before. He looked around, trying to get the image out of his head. Around him, many were dead. Krory, Marie, Miranda, and even Lavi. He saw Tyki, but was surprised to see Mugen through his chest. He looked around for the only one who could of survived, but stopped when he saw the blue-black hair on the other side of the room. Allen ran over to his rival, and saw that he was still alive. "KANDA!" Allen yelled, hugging his friend around the shoulders, surprised when he got no response.
"K-Kanda?" Allen looked at Kanda's face, who's eyes flickered at him. Blood dripped out of his mouth as he coughed.
"A-Allen... You... must get out... The Noah... they... did something... This is the end... Escape into the Ark... like they tired too..." Kanda words were weakening as he spoke, Allen's eyes watered as he listened and refused. "You... have to... Or else... this was all for... nothing... Get out of here... Stupid Moyashi..." Kanda said, his eyes fading as he breathed his last breath. Allen cried out his name as the whole building started to collapse, fires starting up randomly. Allen felt a presence in his mind try to make him move, but he looked over at his friends corpses and held tight to the dead Kanda. He felt Nea try to take over, but he struggled his hardest to not move. He only wished to stay and die with his friends. But Nea wouldn't take none of it.
Allen watched as his body walked on its own through the Ark, not in control as he looked at the many doors that lead to different places. He could feel Nea try to remember something important as he looked through the doors. Then the Ark started to collapse as well, Nea starting to panic as he tried to find the right door. "Come on. Any one of the doors will do. Why did I do such a good job at hiding them?!" Nea said in Allen's voice, desperate and worried. Allen would've been surprised at his tone , but was too numb to do anything. "Allen, stop being a baby! You remember when Mana said to you! You swore to Mana, that you'd never stop no matter what, that you'd keep walking until you died! You're the one who swore!" Nea yelled, Allen instantly taking control and opened the closest door, taking one last look a the crumbling Ark before stepping through the door that lead to who-knows-where.
Allen fell through his memories, literally. Allen couldn't stop falling downward, his memories of his sad life showing all around him. As he started to fall faster, the memories started to fade, getting darker and darker before he was alone in the whiteness of the free-fall he was in. When the whiteness turned to blue sky, he felt his breath stop. He hit the ground on his back, not expecting it. His vision blurred as he tried to regain his breath. From what he could see, he was in a field somewhere. He could make out a town in the distance, but the distance too great for him to walk in his current condition. He laid his head down on the too green grass, wondering why he hated how nice the day was. He closed his eyes, the warm sun and the slight breeze peaceful and luring him to sleep.
"Hey, kid. Are you okay?"
